Abstract (en)
The catheter has force sensors, which are integrated in a distal section and are designed for measuring the magnitude and direction of external force acting on the distal section. The force sensors are attached to a signal processing unit for common measurement signal processing. An individual fiber Bragg grating-fiber (1') is fixed in a sensor holder (5) and has three force sensor regions (7), which form the force sensors cooperating for common measurement signal processing. An independent claim is also included for a force measuring unit for measuring the magnitude and direction of force acting on a mechanical section.
Abstract (de)
Katheter, insbesondere Ablationskatheter, mit in einen distalen Abschnitt integrierten Kraftsensoren, die zur Messung des Betrages und der Richtung einer auf den distalen Abschnitt wirkenden äußeren Kraft ausgebildet und angeordnet und zur gemeinsamen Messsignalverarbeitung an eine Signalverarbeitungseinheit anschließbar sind, wobei in dem Katheter eine in einem Sensorhalter fixierte einzelne FBG-Faser vorgesehen ist, welche drei Kraftsensorbereiche umfasst, die die zur gemeinsamen Messsignalverarbeitung zusammenwirkenden Kraftsensoren bildet.
